This nearly level, somewhat poorly drained soil is on broad, smooth flats on uplands. Areas are irregular
in shape and are small to large in size. Most of the acreage is used for residential and industrial sites. The
rest is wooded. The native vegetation consists of turkey oak, post oak, red oak, water oak, longleaf pine,
loblolly pine, waxmyrtle, gallberry, and pineland three-awn.
Typically, the surface layer is dark gray fine sand 8 inches thick. The subsurface layer is light gray fine sand
4 inches thick. Below this to a depth of 36 inches is fine sand that is dark brown in the upper part, brown
in the middle part, and light gray in the lower part. The subsoil, to a depth of 66 inches, is mottled
brownish yellow sandy loam in the upper part and light gray clay loam in the lower part.
Included with this soil in mapping are small areas of Onslow and Leon soils and a few small areas of soils
that are poorly drained.
The organic-matter content of the surface layer is low. Permeability is rapid to a depth of 36 inches and
moderately slow below. Available water capacity is low, and the shrink-swell potential is low. Reaction is
medium acid to very strongly acid throughout where this soil has not been limed. The seasonal high water
table is about 1.5 to 2.5 feet below the surface.
A seasonal high water table is the main limitation in the use and management of this soil. Supplemental
irrigation and soil conditioners may be needed to establish lawns, shrubs, and trees. Capability subclass
